For all-day comfort and expedition-level sun protection, nothing beats the full coverage of the Patagonia Canvas Sun Cap. The large bill with dark underside blocks rays and knocks down glare, while the fixed-drape flap shields ears and neck. Lightweight, 100% organic cotton breathes easy in tropical heat and a Coolmax headband wicks away tarpon-induced sweat. When it’s time to make the run to your next stakeout, this hat stays firmly in place with an adjustable rear elastic strap and soft chin-strap.
